The tension in the above string is 89.6 N. Calculate the mass of a 4 m long piece of the steel string.
To calculate the mass of the steel string, we can use the following formula:
mass = tension / acceleration due to gravity
In this case, the tension in the string is given as 89.6 N. The acceleration due to gravity is approximately 9.8 m/s^2.
Substituting the given values into the formula:
mass = 89.6 N / 9.8 m/s^2
Simplifying the expression:
mass = 9.14286 kg
Therefore, the mass of the 4 m long steel string is approximately 9.14 kg.
